摘要： Disclosed are a winch, a rope guide, and a transmission device having a clutch function. The winch includes a base seat, a reel, a rope guide, a transmission assembly, and a motor. The reel is rotatably provided to the base seat. The rope guide is provided to the base seat. The transmission assembly is connected with the rope guide. The motor is connected with the reel to drive the reel to rotate, and the motor drives the rope guide through the transmission assembly. In the winch according to embodiments of the present disclosure, the rope guide is an active rope guide, bringing about a good rope guiding effect. Moreover, the reel and the rope guide are driven by the same motor, which reduces the number of components and parts, simplifies the structure and control, and lowers costs.

摘要： A portable winch and method of use is shown. One advantage of winches shown includes an ability to lower a boom or boom sections into limited access exit pit for winching operations such as pipe bursting. Sectional boom designs shown provide the ability to easily raise and lower a boom large distances without the need for a single long boom. Selected winch designs shown include flexible inserts between the boom and the winch frame that help resist damage from unforeseen shifting of the device during operation. Designs and methods shown also include multiple pulleys on a boom end unit. Fasteners are shown that reduce build up of debris.

摘要： A rope guiding device for guiding a rope on a rope drum, the rope drum being adaptable to rotate about a drum axis to wind the rope around the rope drum or from the rope drum to hoist and lower a load adapted on the rope, includes at least guiding element, and an actuator for generating a rope guiding force, which force affects each guiding element in the direction of the drum axis so that the movement of each guiding element in the direction of the drum axis may be guided by the force.

摘要： An apparatus for controlling tension in a pulling rope that is attached to a flying, unmanned aerial device or drone may utilize a cylinder around which the rope is wound, a shaft that longitudinally passes through the cylinder, a disc brake rotor that is mounted to the shaft, a brake caliper that is mounted circumferentially at a periphery of the disc brake rotor, and a brake lever that tensions a cable that is attached to, and movable to control movement of, the brake caliper, which may be hydraulic, against surfaces the disc brake rotor. The brake lever may be hand actuated and mounted to a handlebar. A frame may be part of the apparatus and support apparatus components and may have a protruding hitch portion that inserts into a vehicle's receiver hitch. An adjustable pulling rope guide support through which the rope is threaded, mounts to the frame.

摘要： Example string reels with level wind apparatus are disclosed herein. An example level wind apparatus includes a guide to direct a line onto or away from a reel when the reel is rotating. The reel is rotatable in a first direction to wind the line onto the reel and the reel is rotatable in a second direction to unwind the line from the reel. The level wind apparatus also includes a tensioner to create tension in the line while the reel is rotating the second direction.

摘要： The invention is a mobile winch in a bag system. A motorized winch with an internal battery is mounted on a metal plate that is attached the bottom inner portion of a bag. The metal plate may have attachment points for coupling an anchor component to fix the winch in position during a winching operation. The mobile winch in a bag system provides a way to transport and operate a winch in areas that are otherwise inaccessible by traditional vehicle-mounted winches without the necessity of separately transporting the components of the system and with reduced setup of the components for use.

摘要： A lightweight winch suitable for industrial applications has the motor assembly self-centered with a housing within the winch drum where it may be easily accessed and removed from the winch drum. The winch drum is supported by a bearing means capable of bearing heavy loads in addition to contributing to a compact profile of the winch. The winch comprises an improved, non-load bearing levelwind mechanism for evenly winding cable about the winch drum.

摘要： A winch is described comprising a rotatable drum for winding and unwinding a first cable therefrom. The winch contains a cable-wiping apparatus with one or more actuators are activated when the drum rotates in a direction for winding the first cable onto the drum. A mechanical force may be transmitted from the actuator to a second cable that is operatively connected to a wiper clamp. The wiper clamp compresses around the first cable when the cable is pulled in.

摘要： A winch is described comprising a compressional wiper system activated by a sensor that detects which direction a cable is moving. When the cable is being pulled in, the compressional wiper system tightens a clamp or fastens a rotatable clamping device inside a fairlead. The tightened clamp or fastened clamping device act to decrease the likelihood that dirt, mud, debris, or other materials that adhere to the cable accumulate within the winch, by wiping or scraping off said materials from the cable.
